[QUOTE="osheen, post: 145428, member: 17476"] [b]Do the math, where did 267 come from?[/b] The stock bore and stroke of a YZ250F is 77 X 53.6 which is 249cc. If you add 2mm of bore the displacement changes to 262.7cc. Where did 267 come from? cc= Pi X R squared X stroke. Numbers are changed to cm. 7.9/2=3.95 radius) 3.95 X 3.95 X 3.1416 X 5.36 = 262.73012cc You try it........... [/QUOTE]
